Abstract: A packaging cover includes a baseboard and at least one corner structure. The corner structure includes a first region, a second region, a first fold line, a third region, a second fold line, and a fourth region. The first region has a slit, and one of the corners of the baseboard is inserted into the slit. The second region is folded with the first fold line as an axis to be perpendicular to the first region. The third region has a clamping groove. The third region is folded with the second fold line as an axis to be perpendicular to the first region. The fourth region has a fixing part. After the fourth region is folded with the second fold line as an axis, the fourth region is overlapped with the third region, and the fixing part is inserted into the clamping groove.

Abstract: A cushion includes a first member and a second member. The first member includes a first body and at least one first extending portion. At least one sidewall of the first extending portion has a first protruding portion. The second member includes a second body and a plurality of second extending portions. At least one sidewall of each second extending portion has at least one second protruding portion corresponding to the first protruding portion. When the first member and the second member are assembled, the first extending portion and the second extending portions are staggered with each other. When the first member and the second member move away from each other by a predetermined distance, the first protruding portion is clamped to the second protruding portion.
